Description
The PXI-4496 is a high-performance, PXI Digital Signal Analyzer (DSA) designed specifically for sound and vibration applications. This model is identified by its part numbers 196153F-02L, 779748-01, and 779748-02, indicating the various configurations available.
It features 16 input channels with a 24-bit resolution, providing users with high-precision data acquisition capabilities. The PXI-4496 is equipped with IEPE constant current signal conditioning, making it compatible with industry-standard sensors for measuring sound and vibration signals.
One of the key advantages of the PXI-4496 is its dynamic range, which goes up to 114 dB. This allows for the accurate capture of a wide range of signal amplitudes, from the very small to the very large, without losing fidelity. The device supports a maximum sampling rate of 204.8 kS/s, enabling the precise sampling of high-frequency signals.
The A/D conversion process is based on delta-sigma modulation, which provides high-quality digital representation of the analog signals. This model is praised for its excellent phase linearity and low noise and distortion levels, ensuring that the captured data is both accurate and reliable.
Additionally, the PXI-4496 incorporates both analog and digital antialiasing filters, which automatically adjust to the signal conditions. This feature helps in preventing aliasing, a phenomenon that can introduce errors in the measured signal.
In summary, the PXI-4496 is an advanced sound and vibration data acquisition device, offering high precision, flexibility, and reliability for a broad range of applications. Its robust feature set makes it an ideal choice for professionals working in the field of sound and vibration analysis.
